Remove drives slowly: When removing a drive tray, withdraw it from the enclosure slowly. If the drive tray is removed too quickly a drive I/O timeout might occur.

Replacement on-hand: Before removing a failed hard drive from the subsystem, make sure you have a replacement hard drive readily available. Do not leave the drive tray slot open for an extended period of time. If the drive tray slot is left unoccupied for an extended period of time, the airflow within chassis will be disrupted and subsystem com- ponents will overheat and may become permanently damaged.

Replacing a Hard Drive

 

When a hard drives fails, it needs to be replaced. To replace a hard drive, please follow these

 

steps:

 

 

 

CAUTION!

 

The hard drive is fragile; please always handle with extreme care. Do not drop the hard drive;

 

always be slow, gentle and careful when putting down a hard drive. Only handle the hard drive

 

by the edges, avoid touching any components or connectors.

 

 

 

 

1.

Identify the drive tray that contains a faulty drive that needs to be replaced.

 

 

 

CAUTION!

 

Replacing the wrong drive in an array can fatally fail a RAID configuration. You should identify

 

a failed drive from the RAIDWatch GUI screen, by checking the drive slot ID in the terminal

 

screen, by checking the LEDs on the drive tray panel, and/or use the identify/flash drive func-

 

tion of firmware.

 

 

 

 

2.

Open the front flap. To open the front flap, push the release button at the front of the

 

 

drive tray. (See Figure 6.11) The drive tray front flap will automatically be lifted and the

 

 

drive tray will be dislodged from the chassis.
